Abstract: 22,554. Lanston Monotype Corporation, [Lanston Monotype Machine Co.]. Oct 12. Type, setting.- Relates to machines of the kind described in SpecificationsNo.18,638, A.D. 1899, and Nos. 15,545 and 15,650, A.D. 1906, for making record strips for controlling type casting, setting, and like machines. The justifying-signals for a line are automatically selected and are made during the depression of the resetting-key by the successive depression of two justifying-keys which correspond to the two justification-designating punches. The keyboard is provided with a frame 30, shown diagrammatically in Fig. 25, having chambers 31, 32 in which slide valves 33, 34. Ports 35 in the two chambers are connected by ducts 28 with the cylinders of the dimensioning-punches. Each valve contains a single port 40 which can register with any one of the ports 35. Air is admitted to the chambers behind the valves by ducts 42, 43 upon the depression of two keys 60, the designating- punches 4, 5 being simultaneously actuated through the medium of ducts 25, 26. The position of the valves 33, 34 thus determines which dimensioning- punch is actuated in combination with each designating-punch. The valves may be adjusted either by hand or automatically by means of an index comprising two series of notched disks 61, 62, Fig. 3, mounted on a vertical shaft which is secured to a rotatable carrier 17. The carrier is rotated by gearing from a rack 85, Fig. 9, which is advanced by the line-measuring mechanism after the line has reached a certain length. The rack 85 is secured'to a piston 75 working in a cylinder 76, which is connected by a pipe 77 with a port 78 in the cylinder 10 of the motor units' rack 12. After a certain advance of the rack 12, the port 78 is uncovered and air is admitted to the cylinder 76. The advance of the rack 85 is checked by a pivoted arm 83 which meets a stop on the rack 12. Cooperating with the disks 61, 62 is a verticallysliding bar 102 which is raised step by step by the word-space ratchet 18. Brackets 107 on the bar 102 support horizontally-sliding feelers 105, 106, Fig. 17, which are normally retracted by springs 108. Two pushers 109, carried by a shaft 110 and a sleeve 111 on the shaft respectively, are adapted to move the feelers into contact with the disks which are opposed to them. The shaft 110 and sleeve 111 are connected by arms 112 with the valves 33, 34. The valves are provided with actuating-cylinders 113, Fig. 25, to which air is admitted by the depression of the resetting-key 24. The travel of the valves is thus determined by the disks 61, 62, which are engaged by the feelers 105, 106 and which are so formed as to select the proper justifying-signals for the line. The selected punches are actuated by the successive depression of the keys 60. The depression of the resetting- key causes the return of the rack 12 to initial position, the arm 83 being rocked to permit of this by an air-cylinder 95, Fig. 25. The index-carrier 17 is simultaneously locked by a pawl actuated by a cylinder 101, Fig. 25. The return of the wordspace ratchet 18 and consequently that of the bar 102 is delayed by a holding-pawl actuated from the resetting-key by a cylinder 120.
